Kelvin-Helmhotz clouds? Looking for an ID

[Allan Jeffers]

Hey all. The weather may be quiet around here, but I still have my head stuck in the clouds. Tonight on the way to work, I looked out my window and seen what I thought where Kelvin-Helmholtz clouds, so while stuck in the back seat going 40, I stuck my camera out the window and took some shots, forgetting I had my lens in manual focus. I do get some shots but not as sharp as I wanted, but that could have been because of the moving car I was in. They did not last long, perhaps under 2 minutes, so when we got parked, I kept my eyes open for a bit.

BTW, I have seen these clouds around here a few times, usualy with out a camera in hand or they break apart before I get the shot.

Are these KH clouds?

They look like it to me, though they are the most textbook example. Did you notice them "curling" with time? Judging from the shapes, I assume you did, though they look small enough that it may not have been easy to watch. I've seen KH waves from the NWC in Norman a few times in the past year or so. Pretty neat stuff!

You are correct, sir!

Thanks for the ID
